1. Which of the following could be the coordinate point for a function whose inverse has a coordinate point at (2, 7)? (1 point)O (-2,-7)(2,7)cannot determineO (7, 2)

The trigonometric ratios gives the values required.

The three main trigonometric ratios that we need are the sine the cosine and the tangent.

1) The hypotenuse is;

c^2 = 5^2 + 12^2

c = √5^2 + 12^2

c = 13

Then;

sin x + cos x

= 5/13 + 12/13

= 17/13

2) The adjacent is;

13^2 = x^2 + 5^2

x^2 = 13^2 - 5^2

x = √13^2 - 5^2

x = √ 169 - 25

x = 12

Cos p = 12/13

3) The adjacent is;

13^2 = x^2 + 12^2

x^2 = 169 - 144

x = 5

2sinx + 1/2Cos x

2(12/13) + 1/2 (5/13)

144/13 + 5/26

=293/26

The calculated volume of the prism is 702 cubic cm

From the question, we have the following parameters that can be used in our computation

The trapezoidal prism (see attachment)

The formula of the volume of a trapezoidal prism is

Volume = Base area * Height

Where we have

Base area = 1/2 * (8 + 10) * 6

Evaluate the sum of 8 and 10

Base area = 1/2 * 18 * 6

Evaluate the products of 1/2, 18 and 6

Base area = 54

Also, we have

Height = 13

So, the volume is calculated as

volume = 13 * 54

Evaluate

volume = 702

Hence, the volume of the prism is 702 cubic cm

Possible expressions for the length and the width of her pantry floor are x + 3 and x + 8

The function given for the area of the rectangular pantry floor is expressed as;

Area = x2 + 11x + 24

Now, let's solve the quadratic equation using the factorization method

Multiply the coefficient of x squared by the constant + 24

Then, find the pair factors of product that sums up to 11 and substitute the values

We get;

x² + 8x + 3x + 24

Factor in pairs, we have;

(x² + 8x) + (3x + 24)

Now, factor the common terms, we have;

x( + 8) + 3(x + 8)

Then, the expression for x are;

Length = x + 3

Width = x + 8

Hence, the expressions are x + 3 and x + 8

The correct table that shows the ratios in kindergarten classrooms a three-column table is the last one: Brown 10 12 15 32 Green 18 23 35 64 Total 28 35 50 96

The ratios of brown to green crayons in the four kindergarten classrooms are correctly represented in this table, making it accurate. The initial ratio is 10:18, meaning there are 18 green crayons for every 10 brown crayons. The second ratio is 12:23, meaning there are 23 green crayons for every 12 brown crayons. The third ratio, 15:35, states that there are 35 green crayons for every 15 brown crayons. The fourth ratio is 32:64, meaning there are 64 green crayons for every 32 brown crayons.

The chart also displays the correct total quantity of crayons—the sum of the quantities of brown and green crayons—in each classroom. For instance, the total number of crayons in the first classroom is 10 + 18 = 28, the total number of crayons in the second classroom is 12 + 23 = 35, the total number of crayons in the third classroom is 15 + 35 = 50, and the total number of crayons in the fourth classroom is 32 + 64 = 96.

The solution is:  the rate of change is 3.

Here, we have,

Since the graph of f(x) is translated 1 unit down, we need to decrease the value of f(x) by 1 to find g(x):

g(x) = f(x) - 1

f(x) = 3|x| – 4

so, we get,

g(x) = 3|x| – 4 - 1

      = 3|x| – 5

Now, to calculate the rate of change over the interval 2 <= x <= 5, we can use the formula below:

rate = g(5) - g(2)/ 5-2

so, we get,

rate = 9/3 = 3

Therefore the rate of change is 3.

-15x and 15x is the answer

Answer:

-12y and 12y

Step-by-step explanation:

lets do the multiplication to each equation

\(\left \{ {{(6x+3y)(-4)=9(-4)} \atop {(5x+4y)3=10(3)}} \right.\)
this is
\(\left \{ {{-24x-12y=-36} \atop {15x+12y=30}} \right.\)
if we add the systems notice the values that do cancel are -12y and 12y
and the results of the adition is
\(-9x=-6\)
from this
\(x=\frac{-6}{-9} =\frac{2}{3}\)
and you can find y from any of the first equation.

\(y=3-2x=3-\frac{4}{3} =\frac{5}3}\)

i think its going to be 180* degreas! sorry if im wrong

Step-by-step explanation:

The correct answer is, by choosing a = -2 and b = 1, we satisfy both inequalities .a < b:

To make both inequalities true, we need to select values for a and b that satisfy the given conditions:

a < b: This inequality means that the value of a should be less than the value of b.

|b| < |a|: This inequality means that the absolute value of b should be less than the absolute value of a.

One possible solution that satisfies both conditions is:

a = -2

b = 1

With these values, we have:

-2 < 1 (a < b)

|-1| < |2| (|b| < |a|)

Therefore, by choosing a = -2 and b = 1, we satisfy both inequalities.a < b:

This inequality states that the value of a should be less than the value of b. In other words, a needs to be positioned to the left of b on the number line. To satisfy this condition, we can choose a to be any number that is less than b. In the example I provided, a = -2 and b = 1, we can see that -2 is indeed less than 1, fulfilling the requirement.

|b| < |a|:

This inequality involves the absolute values of a and b. The absolute value of a number is its distance from zero on the number line, always resulting in a non-negative value. The inequality states that the absolute value of b should be less than the absolute value of a. To satisfy this condition, we can choose b to be any number with a smaller absolute value than a. In the example I provided, |1| is less than |(-2)|, as 1 is closer to zero than -2, fulfilling the requirement.

By selecting a = -2 and b = 1, we satisfy both inequalities: a < b and |b| < |a|. The specific values of -2 and 1 were chosen as an example, but there are multiple other values that would also satisfy the given conditions. The important aspect is that a is indeed less than b, and the absolute value of b is smaller than the absolute value of a.

we know that

If two lines are perpendicular, then the product of their slopes is equal to -1

so

The given line is

2y+6x=12

step 1

Find the slope

isolate the variable y

2y=-6x+12

y=-3x+6

the slope is m=-3

therefore

the slope of teh perpendicular line is

m=1/3

step 2

Find the equation of the line in point slope form

y-y1=m(x-x1)

we have

m=1/3

(x1,y1)=(-3,7)

Answer:

Given:

Area of the sector (A) = 104π/9 square inches

Central angle (θ) = 65 degrees

The formula for the area of a sector of a circle is:

A = (θ/360) * π * r^2

We can rearrange this formula to solve for the radius (r):

r^2 = (A * 360) / (θ * π)

Plugging in the given values:

r^2 = (104π/9 * 360) / (65 * π)

r^2 = (104 * 40) / 9

r^2 = 4160 / 9

r^2 ≈ 462.22

Taking the square root of both sides:

r ≈ √462.22

r ≈ 21.49

Therefore, the radius of the circle is approximately 21.49 inches.

Though the difference is not numerically significant, it is important to unitary method keep in mind that there might still be a real difference that this group does not account for.

The unit method is a strategy for handling issues that entails first figuring out the value of a single unit, then multiplying that value to figure out the needed value. Simply stated, the unit method is used to extract a unique unit number from a multiple that is given. For example, 40 pens would cost 400 rupees, which is equal to the expense of one pen. This procedure might follow a conventional procedure. a distinct nation. anything with a distinct character. Its adjoint and inverse are identical in terms of mathematics, algebra, linear algebra, mathematical analysis, or mathematics of matrices or operators.

The disparity in reaction latencies between conventional incandescent lights and LED lights has a 99% confidence range of (-30.83, 271.17) milliseconds. We cannot definitively determine whether the average difference is positive or negative because the interval includes both positive and negative numbers.

The best conclusion is option 5, which states that there isn't much of a difference between the two kinds of lighting's typical response rates.
